pre-conditioning…
•Precursor to all Dermodality TCA/Jessner peels (No Exceptions)
•Builds tolerance
•Prepares the skin to tolerate deeper peels
•Provides predictable success of treatments
•Pre conditioning is necessary for Level 2&3 peels
chemical peels trigger the wound repair response, if skin is pre-conditioned chemical peels only cause minimal damage to epidermis…
pre-conditioning chemical peels
*Fernandes, D. OralL Maxillofacial Surg Clin 2005;17:51-63.
• Pre-conditioning minimizes the risk of hyperpigmentation
• Only temporary disruption of the skin barrier function
• Minimizes downtime
• Pre-conditioning offers a simple and safe way to improve the appearance of the skin without risk of pigmentation issues in patients of all skin types

melaninMelanin is the pigment primarily responsible for skin color Melanocytes are melanin producing cells located in the basal layer of the epidermisMelanogenesis is triggered by inflammation from UV, hormones, stress and injury.Melanin’s primary function is to protect the hypodermis from UV-light that causes DNA photodamage.Light and dark pigmented skin is not due to the quantity of melanocytes but to the amounts of eumelanin and pheomelaminEumelanin-most abundant type of human melanin, found in brown and black skin Pheomelanin- melanin found in light skin and red hair
tyrosinase• Tyrosinase is an enzyme that catalyzes the production of melanin from tyrosine by
oxidation• Tyrosinase is located in melanocytes• Tyrosinase is a copper-containing enzyme• Tyrosinase is required for melanocytes to produce melanin from the amino
acid tyrosine
• Tyrosinase is stimulated by various inflammatory factors:UV (sun exposure)Hormones (87% of pregnancies develop melasma)Contraceptive drugs (80% develop melasma)StressHeredityChemically/Heat based treatmentsInjuryAcne Dermatitis
hyperpigmemted/sun damaged skinDISEASE PRESENTATION
A – melanocytes in the basal layer produce melanin (pigmentation) and deposit on melanosomes, which are transferred to keratinocytes, breaking into pieces. Melanocytes are affected by heredity, hormones, light energy, and other factors.
B – The pigment we see are fragments of keratinocytes, which are moving through the stratum corneum. The stratum corneumbuilds up and these fragments become trapped and cluster in the upper layers of skin.
• Freckles• Sun spots, “age” or “liver” spots• Uneven completion• Melasma (dark discoloration)• Acne spotting• Dyschromia (abnormal skin
color)• Chloasma (patchy brown or
dark brown –hormonal/pregnancy)

melanogenic cascade1. Start of melanogenesis: inflammation processes
2. Melanocyte produces tyrosine which is converted by the tyrosinase
3. Tyrosinase converts tyrosine to L-DOPA (L-dihydroxyphenylalanine)
4. Dopachrome is converted to DHICA (intermediate in the biosynthesis of melanin)
5. Melanin production

oxidation
• Tyrosinase is responsible for melanin production from tyrosine by oxidation
If the tyrosine in a banana is responsible for the yellow color of the peel, tyrosinase is responsible for causing the peel to turn brown. If tyrosine is responsible for skin pigmentation, tyrosinase is responsible for hyperpigmentation…
inflammatory triggers• Sun is responsible for most skin hyper-pigmentation
• Sun, stress, hormones, inflammation from treatments/trauma cause hyperpigmentation
• Skin can hyper-pigment from any kind of stress especially hormonal imbalances
• Hormones play a role in regulating pigment production (pregnancy/birth control meds)
• Stress hormones: epinephrine and norepinephrine (neurotransmitters) dependent on Tyrosine
• Body responds the same to any kind of stress
• Triggers are: inflammation due to treatments, hormones, stress, sun exposure, injury, sugar/synthetics in the diet, too much caffeine lack of antioxidants

tyrosinase inhibitors
• An important antioxidant in animals• One of the most important cellular antioxidants• Glutathione prevents damage caused by free radicals• Produced in the body and made from the amino acids cysteine, glutamine and
glycine• Used in metabolic/biochemical reactions such as DNA synthesis and repair• Binds to Tyrosinase and helps prevent the enzymatic pathways from producing
melanin• Its antioxidant properties eliminate free radicals and inactivate tyrosinase • Helps prevent the activation of tyrosinase by reducing free radicals that activate
and cause an increase in melanin production• Melanin is the pigment that gives our skin its color, produced by the activation of
the enzyme Tyrosinase• Can be applied topically or as an oral supplement
glutathione:
tyrosinase inhibitors
hydroquinone:• Hydroquinone is considered the gold standard
• Hydroquinone inhibits melanin synthesis (tyrosinase inhibitor)
• Commonly used at concentrations of 2-4% (4% requires prescription)
• Clinical studies report good responses at 2%
• Higher concentrations are effective but can cause irritation
• Safely combined with retinoids
• Agency for Research on Cancer does not classify as a carcinogen in humans
tyrosinase inhibitors
kojic acid:• Derived from natural fungus (mushroom)
• Reduces hyperpigmentation (inhibits tyrosinase production)
• Potent antioxidant
• Used at concentrations from 1% to 4%
• KA and HQ in combination, with glycolic acid, improve efficacy
• Patients not responding to HQ may benefit by adding KA to treatment
tyrosinase inhibitorsalpha arbutin:
• Alpha-arbutin widely prescribed de-pigmenting agent worldwide
• Naturally occurring plant derived compound: bearberry, blueberry, cranberry, pears
• Inhibits tyrosinase and melanosome maturation (transporters of melanin)
• Less cytotoxic to melanocytes than hydroquinone
• Less effective than kojic acid for hyperpigmentation when used alone
tyrosinase inhibitorsl-ascorbic acid:
• Vitamin C is a naturally occurring antioxidant
• Interacts with copper ions at the tyrosinase active site
• A “reducing agent” at various oxidative steps of melanin formation
• Inhibits melanogenesis
• Reduces tyrosinase activity by antioxidant activity (not by inhibiting tyrosinase)
• Magnesium-ascorbyl-phosphate (MAP) is lipophilic, stable vitamin C derivative absorbed through the stratum corneum
tyrosinase inhibitorsalpha tocopherol:
• Photo-protective effects
• Causes depigmentation by interference with lipid peroxidation of melanocytes
• Increases intracellular glutathione and inhibits tyrosinase
• Improves melasma and pigmented contact dermatitis used with vitamin C
tyrosinase inhibitorsniacinamide:• Also known as nicotinamide
• A component of niacin (vitamin B3)
• Required for cellular metabolism
• Interferes with the interaction between keratinocytes and melanocytes
• Inhibits melanogenesis
• Modulates the enzyme involved in transfer of melanosomes from melanocytes to keratinocytes
• 2% niacinamide reduces the hyperpigmentation and increases skin lightness after 4 weeks
• Niacinamide with sunscreen is more effective reducing hyperpigmentation than sunscreen alone
tyroinase inhibitors
aloe vera:• Active ingredient is aloin made from the whole leaf
• Leaf extract has melanin accumulating effects leading to skin lightening
• Aloesin is a natural derivative of aloe vera
• Inhibits tyrosinase at non-cytotoxic concentrations
• Aloe vera extract is a common ingredient often used in place of water
tyrosinase inhibitorsflavonoids:
• Naturally occurring polyphenolic compounds
• Anti-inflammatory, antioxidant, antiviral and anti-carcinogenic properties
• Gallic acid (from green tea leaves)
• Ellagic acid (from green tea, eucalyptus, strawberry, etc.)
• Aloesin (from aloe tree)
tyrosinase inhibitorsgreen tea extract:
• Contains polyphenolic compounds that act on various biochemical pathways
• Anti-inflammatory, anti-oxidant and anti-carcinogenic effects
• Gallic acid is the main active ingredient in green tea
• Green tea extracts cause inhibition of mushroom tyrosinase
• Responsible for the de-pigmenting effect on the skin
tyrosinase inhibitorslicorice extract:
• Licorice extract is obtained from the root of Glycyrrhia Glabra Linnera
• It is cultivated extensively in India
• Improves hyperpigmentation by dispersing melanin
• Inhibits melanin biosynthesis
• Decreases free radical production and has anti-inflammatory effects
• Glabridin, a polyphenolic flavonoid is the main component and prevents Ultraviolet B (UVB) induced pigmentation
tyrosinase inhibitorsretinoids:
• Derivatives of vitamin A
• Inhibit tyrosinase and epidermal melanin dispersion
• Interfere with pigment transfer to keratinocytes
• Accelerate pigment loss by causing the epidermis to shed quickly
• Increases stratum corneum density and decreases melanin
• Improves melasma used with corticosteroids, hydroquinone, retinoic acid
• Retinoids facilitate epidermal penetration and delivery of hydroquinone
tyrosinase inhibitors
sun protection:• Broad spectrum sunscreens are the cornerstone of
hyperpigmentation therapy
• Minimize inflammation caused by UV exposure
• Opaque substances, zinc oxide and titanium dioxide, reflect and scatter most of the UV rays
• Chemical sunscreens absorbs light in the UVA range
